Abstract

857,058. Making helical screw-thread inserts; coiling. HELI-COIL CORPORATION. May 6, 1959 [Dec. 3, 1958], No. 15483/59. Classes 83 (2) and 83 (4). [Also in Group XXV] A helical screw-thread insert is made by coiling a plurality of convolutions of equal pitch and diameter, then forming a chordal portion or portions by stretching the wire against a straight-lined surfaced portion or portions of a support and then continuing coiling convolutions of the first-mentioned kind. The end 42 of diamond-sectioned wire 41 is inserted in an undercut transverse slot 31 at the end of a mandrel 30 which is then rotated so that the wire coils in a helical groove 36 on the mandrel. The groove 36 has a straightline chord forming part 38 of a helix angle slightly greater than that of the rest of the groove, being cot <-1> (#DN) where D is the inside diameter of the coil and N the number of convolutions per inch of coil length. The part 38 forms a straight line chordal portion 12 in the insert during coiling. A second straight line portion separated from the first by a helical portion or a plurality of closely adjacent chordal portions 21 may be formed during coiling.
